Since .losing the use of my left arm & hand, I try very hard to never get a splinter; but, inevitably it happens every now & then. Of course, the splinter is enbedded in my working hand & I cannot hold the tweezers with my non-working hand. I read a lot about different ways to remove splinters until I finally found one that worked for me. I use a piece of clear tape. I press the sticky side of the tape onto the area with the splinter pressing the covered area well. Then I grab the corner that will pull in the same direction as the splinter & pull it really fast. The majority of the time, the splinter is stuck to the tape. I can do this one because I can grab the corner of the tape with my teeth & pull without needing to use my non-functioning hand!!!
Another I read but haven’t tried because I think it would keep the tape from sticking is to take a banana skin & place the inside of the skin onto the splinter, & leave it on for about an hour. This is similar to soaking in water in that it causes the splinter to swell & it also enlarges the hole the splinter made. Then you take the tweezers & slide the splinter out. I would think this would be easier than soaking the area in water as you’re not as limited to what you can do while waiting for the end result.
Back in the good old days when I could get the splinter out with tweezers, I found it helpful to take the point of the tweezers or even a sewing needle & press near the bottom of the splinter toward the entry point. This would often push a portion of the splinter up just enough that I could get a better grasp of the end of the splinter with the tweezers. The needle worked best at pushing the splinter up as I could roll it against the embedded end of the splinter & the splinter slid out easier.
The only thing worse than having a splinter to begin with is to have one of those tiny little suckers that you really can’t see very well!!!
Good luck getting yours out!!!
